Answer:
(1,1)
Step-by-step explanation:
we have
we know that
If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality
<u><em>Verify each ordered pair</em></u>
case A) we have
(5,0)
Substitute the value of x and y in the inequality
----> is not true
therefore
The ordered pair is not solution to the inequality
case B) we have
(0,-2)
Substitute the value of x and y in the inequality
----> is not true
therefore
The ordered pair is not solution to the inequality
case C) we have
(1,1)
Substitute the value of x and y in the inequality
----> is true
therefore
The ordered pair is a solution to the inequality
case D) we have
(-5,-6)
Substitute the value of x and y in the inequality
----> is not true
therefore
The ordered pair is not solution to the inequality
A petri dish is simply a circle; thus, we use the formula of the area of the circle which is <span>πr^2.
Given r = 40 mm
A = </span>π(40)^2 = <span>5026.55 sq. mm
</span>
Population density = bacteria count / area
PD = 2,100 / <span>5026.55
PD = </span><span>0.417782 bacteria / mm sq.
Therefore, the answer is approximately 0.418 </span><span>bacteria per square millimeter.</span>
Answer:
$5 per flower
Step-by-step explanation:
25/5=5
First of all, 2^n and 3^n are exponentials with different bases, and thus their sum cannot be simplified beyond 2^n + 3^n. In other words, these two functions cannot be combined ino one function (such as 4^n).
You may gain much more insight by graphing 2^n, 3^n and 4^n to determine whether there is truth in the given statement or not.
The answer is 50
The ratio of boys to girls is 10:25 in the school
If sample has 20 boys (10x2) then based on ratio it would likely have 50 girls (25x2)
